| 摘 要： | 以宿州市街道路面灰尘为研究对象,利用X射线荧光光谱法测定其Pb含量,探讨其分布特征及来源,通过Pb污染指数法和富集因子法评价Pb污染水平。结果表明:Pb含量的变化范围在38～75mg/kg,平均值为51.20mg/kg;分布上,高值区出现在人流量、车流量密集的商业区以及车站附近;宿州市街尘Pb污染为无污染到中度污染水平,由于Pb累积趋势的存在,对环境质量存在一定的隐患。

| Abstract: | Concentrations,distribution characteristics and source of Pb in street dust from different function zones of Suzhou city were determined by X-Ray fluorescence spectrometer,lead pollution index and enrichment factor.The results show that the range of lead content in street dust is 38～75 mg/kg,with average value of 51.20 mg/kg,which is 1.92 times of the soil lead background value in Anhui province;the content of lead from business district and bus station are relatively higher;results of lead pollution index and enrichment factor assessment show that the Pb pollution in street dust in Suzhou city belongs to light～medium level pollution. |
